Due to our supplier discontinuing the R27 encoders (TTL type, 3 channel / 500 line) used on our original RK series and CRK series board type geared motors, including the motor only models of these lines, Oriental Motor USA is discontinuing these motors effective Friday, 2/5/2016. This does not affect the Line Driver type or DC type 5 phase encoder motors (except geared types) in these packages or motor only.

For replacement options, please first check the newer RK2 series or CRK series. The AR series (AC or DC input) is a great plug & play alternative to the RK2 (AC input) or CRK series (DC input) since it offers self-contained, high performance closed-loop operation without having to set up any parameters. Just connect the cables, supply power, and it's ready to go. The AZ series is an even newer version of the AR series which keeps the closed-loop and high efficiency features of the AR series then adds an absolute sensor for tracking absolute position or homing the motor quickly without an external sensor.
